 === Bug Fixes
 
+Machine Learning:: 
+* By-fields should respect model_plot_config.terms {ml-pull}86[#86] (issue: {issue}30004[#30004])
+* Function description for population lat_long results should be lat_long instead of mean {ml-pull}81[#81] (issue: {ml-issue}80[#80])
+* Fix error causing us to overestimate effective history length {ml-pull}66[#66] (issue: {ml-issue}57[#57])
+* Clearing JSON memory allocators {ml-pull}30[#30] (issue: {ml-issue}26[#26])
+* Fix sparse data edge cases for periodicity testing {ml-pull}28[#28] (issue: {ml-issue}20[#20])
+* Impose an absolute cutoff on the minimum variance {ml-pull}8[#8] (issue: {ml-issue}488[#488])
+* Check accesses in bounds when clearing recycled models {ml-pull}79[#79] (issue: {ml-issue}76[#76])
+* Set forecast progress to 100% and status finished in the case of insufficient history (data) {ml-pull}44[#44]
+* Add control message to start background persistence {ml-pull}19[#19]
+* Fail start up if state is missing {ml-pull}4[#4]
+* Do not log incorrect model memory limit {ml-pull}3[#3]
+
 Security::
 * Reduces the number of object allocations made by {security} when resolving the indices and aliases for a request ({pull}30180[#30180])
 * Respects accept header on requests with no handler ({pull}30383[#30383])
